to start with the horizon needs to be horizontal and not slanting as this one is.
Next, the composition doesn't really work for me. Everything is moving across left to right with nothing to allow the eye to stop and enter the image. The fence is also a visual barrier.
You need to work harder at finding angles and different heights to take the picture at so the image becomes more interesting and allows the viewer to be drawn into it. At the moment it is at the level of a snapshot.
You have three basic elements you have to consider for the composition:
the shoreline rocks
The light is a major factor in an image and how it links or isolates subjects.
The first thing to think of is what is your subject matter. Is it the bridge or the fence and what of these takes priority? Then what can I leave out of the image and still get across my intentions. Once you have worked this out it is then that you can start to arrange the elements for the composition within the viewfinder. What you see now has boundaries and is directly related to shape and format of the viewfinder. It is how you compose these elements together with that shape that will create success or mediocrity.
A landscape generally needs, foreground interest (which can be a rock, an unusual piece of wood etc.), mid ground ( which links the f/g to the b/g ) and b/g interest. A killer sky helps a lot too. Lines that converge to some point of interest are helpful in making an image more dynamic. Diagonal lines are generally seen as being unstable within a composition and creating a dynamic image.
There are many books on composition that will give you help with line, shape, form, colour, tone, dynamics and texture to name just a few things you have to be aware of. This site has tutorials on composition which will help you and the many landscape photographs you see on epz can, if you approach them with a critical mind, give you valuable ways of composing elements for next time you take photographs.
I hope this hasn't upset you as you did ask for a crit and this is only an opinion anyway.
Kind regards, Alan.
